TAKE-DOWN FOR MACHINE-DRAWN CYLINDERS.

Specification of Letters Patent.

Patented Oct. 15, 1918.

Application filed February 11, 1918. Serial No. 216,600.

To all whom it may concern:

' Be it known that I, HENRY J. DOUOHAMP, a citizen of the United States,residing at Smethport, in the county of McKean and State ofPennsylvania, have invented a new and useful Take-Down for Machine-DrawnCylinders, of which the following is a specification.

The object of my invention is to produce an efficient device, by meansof which the completed cylinders of glass, produced by machine drawingmethods, may be readily taken down from their vertical position to ahorizontal position and deposited upon a suitable horse, the mechanismbeing of such character as to be controllable by a single operator,conveniently the operator who has control of the drawin apparatus.

The accompanying rawings illustrate my invention. Figure 1 is a sideelevation, largely diagrammatic in character, of an apparatus embodyingmy invention, and Fig. 2 is a similar view of substantially the sameapparatus having, however, a lower track for the take down trolleys.

In the drawings, 10 indicates a tract extending outwardly from a pointnear the drawing apparatus and substantially parallel with the horse 11,upon which the completed glass cylinder 12 is to be deposited in ahorizontal position. The track 10 may be of any desired character,either rigid, or somewhat vertically flexible, in which case the trackwill be formed of a cable supported at its ends only. This track may belocated at any convenient height, depending somewhat upon the characterof the building in which the apparatus is placed, so long as itissuificiently high to clear the down-coming cylinder.

The cylinder 12 may be produced by any form of drawing apparatuscomprising a hoisting mechanism 13, by means of which a bait 14 may beassociated with the bath 15 and raised in a proper manner to cause theformation of a cylinder. In the drawings, I have illustrated thisapparatus as of a well known type, wherein the hoisting apparatus 13 is.guided in a swinging guide 16, the lower end of which may be swungoutwardly, preliminary to the take down operation. so that the downwardline of travel of the bait is somewhat inclined, relative to thevertical. While I have found that this particular arrangement is aconvenience in the take down operation, it is by no means essential.

Mounted upon track 10 are two carriages, or trolleys, 17 and 18, whichcarry swivelecl pulley blocks 17 and 18, respectively. The travel ofcarriage 17 on track 10 is limited by means of stops 19 and 20, and thetravel of carriage 18 is limited by stops 21 and 22. Passing over, andsupported by, the pulley of block 17, is the bait-end take-down-cable23, which is provided at its free end with a hook 24 which may be hookedinto an eye 25, carried by bait 14. Passing over, and supported by, thepulley of block 18 is the holeend' take-down-cable 26 which is providedat its free end with a hook, yoke or hoop 27 which may be slipped over,or associated with the hole-end of cylinder 12 in a manner common in theart. 7

I have found it desirable to reduce as much as possible the pullingeffect of cables 23 and 26 upon the carriages 17 and 18 longitudinallyof the track 10, and I have therefore found it convenient to carry thesecables 23 and 26 down through the floor 28 to one side of the horse 11,of course leaving passageway between these cables and the horse. Cable23 is passed beneath a guide pulley 29 and over a guide pulley 30,passing also beneath guide pulley 3O alongside of cable 26, which iscarried beneath guide pulley 30. The two cables 23 and 26 are connectedtogether at 31 and from that point continue as a single cable 32 to awinding drum 33, which may be conveniently electrically driven, so thatit may be controlled from a distant point, such, for instance, as thecontrolling pulpit of the drawing apparatus (not shown). It will bereadily understood that considerable variation may be had in the mannerof operating the two cables 24 and 25 without departing from myinvention.

The lengths of the two cables 23 and 26 are determined primarily by thedistances between the rearmost positions of carriages 17 and 18, and thebait-end of the cylinder and the point of normal association of the hoop27 with the hole end of the cylinder, when the cylinderis on the horse11, the cables being so adjusted in lengths, relative to their point ofjunction 31, that the cylinder may be raised and lowered in a substan-23 and 26 may" be drawn forwardly to the required amount. Hook 24 isthenassociated with eye 25 of bait 14, some time during or priorto, itsrise in the drawing operation. Whenthe cylinder 12 has been:

completed, the hoop 2'? will be associated with the hole end of thecylinder in the man;-

ner indicated in full lines in the drawings, or this associationmay bedelayed until the lower" end of guide 16 has been swung to thepositionindicated in dotted lines-in Fig. 1, if the apparatus is equippedwiththisswing-ing cage guide.

in cables 23 and. 26', this operation taking place with a speedcoordinated with the lowering movement of the bait until the cylinder 12is drawn out nearly to a hori-- zontal position, as indicated by theposition A, at which timecable123 will have-all ofits' slack taken upand be tightenedupon the bait I4, whereupon the bait will be drawn awayfrom its'hoisting apparatus 13 and the cylinder will swing automaticallyto the position B, Where it is substantially horizontal and verticallyabove the horse 1 1. It may be that at times the automatic out wardswing of the cylinder 12 may not be quite far enough to bring thecylinder di rectly vertically above the horse, in which case a slightpush lengthwise of thecylind'er will cause the carriages 17" and 18 tomove outwardly along track 10, until thecylinder isvertically above thehorse, whereupon a backward movement of the winding ap parat'us- 13-will serve to lower the cylinder to the-position C on horse 11". Wherethe track 10 is elevated to a point above the highest draw point, it isadvisable, in order to prevent an upward slipping of the hoop 27 duringthe-early't ake down movement, to provide a pulley 35 underwhich thecable 26 must bepassed in order to associatethe hoop with thecylinder.Where the track 10" is located at a lower point, as indicated in 2, thepulley 35 may be dispensed wit I claim asmy invention I. A take-downapparatus comprising means forl'owering'the bait-end of the cylinder, anelevated track extending outwardly relativeto this means, two independ-Thereupoir, the op erator will lower bait 12L and at the same time drum33 will be operatedso as to draw ent carriages mounted on said track atdifferent points in its length, and each of said carriages carrying a.support over which a cable may be passed, a bait-end cable passed overthe cable support ofone of said carriages'and provided with means forengaging, the bait end of the cylinder, a hole-end cable passed over thecable support of the other carriages and provided with means to engagethe hole end: of the cylinder, and means for taking up the slack in saidcables during lowering ofthe bait'en'd of thecylinder, aud tor payingout said cables to low er the cylinder after'it' has been separated fromits initial lowering; means;
